Embodiment 1

[0027] figure 1 It is a flow chart of a screen information monitoring method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the screen is controlled when the network is abnormal or the video line from the screen controller to the screen is damaged. This method can be controlled by the screen information The monitoring device is implemented, and the device can be configured on a network camera.

[0028] Such as figure 1 As shown, the screen information monitoring method provided in the embodiment of the present invention may include:

[0029] S101. Analyze the information content displayed on the screen collected in real time, and match the analysis result with the pre-stored standard content.

[0030] In the embodiment of the present invention, firstly, the monitoring of the screen by the network camera and the pre-processing of intelligent analysis must be completed. For example, the relationship between the screen c...

Embodiment 2

[0045] figure 2 It is a schematic flowchart of a method for monitoring screen information provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above embodiments, such as figure 2 As shown, the screen information monitoring method provided in the embodiment of the present invention may include:

[0046] S201. Analyze the information content displayed on the screen collected in real time, and match the analysis result with the pre-stored standard content.

[0047] Among them, the standard content is the information to be displayed that has been approved and sent to the network camera by the video supervision platform. As an optional implementation, the structured feature information analyzed and extracted by the video supervision platform from the reviewed information to be displayed can also be used as standard content.

[0048] S202. According to the matching result, it is judged whether there is abnormal content in the curre...

Embodiment 3

[0061] image 3 It is a schematic structural diagram of a screen information monitoring device provided in Embodiment 3 of the present invention. The device is configured on a network camera, and the network camera is equipped with an infrared supplementary light lamp bead capable of being controlled.

[0062] Such as image 3 As shown, the device includes:

[0063] The analysis and matching module 301 is configured to analyze the information content displayed on the screen collected in real time, and match the analysis result with the pre-stored standard content, wherein the standard content is information to be displayed that has been approved;

[0064] An abnormality judging module 302, configured to judge whether there is abnormal content in the currently displayed information according to the matching result;

[0065] The control module 303 is configured to control the infrared supplementary light bead to emit an infrared remote control signal to the infrared receiving...

Abstract

The embodiment of the invention discloses a screen information monitoring method and device, a network camera and a storage medium, and the method comprises the steps: analyzing the information content, collected in real time, displayed on a screen, and enabling an analysis result to be matched with the pre-stored standard content which is the to-be-displayed information which is approved; judgingwhether abnormal content exists in the currently displayed information or not according to a matching result; if so, controlling the infrared light supplementing lamp bead to emit an infrared remotecontrol signal to an infrared receiving controller of the screen so as to control the abnormal content displayed by the screen. According to the embodiment of the invention, the screen content is directly subjected to safety monitoring through the network camera, the manual check investment is reduced, and the screen can be directly controlled even if the network is abnormal or the video lines ofthe screen controller and the screen are damaged.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of monitoring, and in particular to a screen information monitoring method, device, network camera and storage medium. Background technique [0002] Large LED screens (composed of multiple displays) in public areas are often deployed in areas with relatively large traffic, and the displayed content is generally important text information and relatively fixed video promotional films, advertisements, etc. When the information uploaded to the big screen contains sensitive or illegal information, its social impact is relatively large. How to conduct real-time supervision on the information uploaded to the large screen has become a difficult problem in urban improvement, and these large screens are often deployed outdoors / roads, etc. When sensitive information or image quality problems appear, it is difficult to control and adjust the image quality in a timely manner . [0003] At pres...
